Overview
The OS1st AC4 Active Comfort 1/4 Crew Socks are designed to deliver cushioned comfort all day long. Featuring extra cushioning in the heel and toe areas, the socks are made from soft bamboo charcoal fibers for a highly comfortable fit. An ultra-thin Skin Thin™ panel along the top helps to promote airflow and regulate temperature for optimal breathability. Additionally, the seamless construction is treated with silver-ion technology to keep you dry and prevent odor. To prevent the socks from slipping down, a Y-Gore heel is integrated into the design.

Sock Thickness
- Thin: Thin socks are typically ultra-lightweight, highly breathable, and quick-drying. These socks are ideal for snug-fitting shoes, like racing or competition options, or for the runner who prefers a more minimal approach to their footwear.
- Medium: Medium-thickness socks offer a blend of cushioning, moisture-wicking, and added comfort. These socks work well for most runners and can provide an extra sense of protection in everyday running shoes.
- Thick: Thick socks provide full cushioning for a plush ride and extra comfort. These socks are useful for runners looking for underfoot protection or those who are looking to remove any extra space in their shoes.
Sock Height
- Low: Low-cut socks go no higher than the middle of the anklebone. No-show socks, which do not go higher than the top of your shoes, are also in this category.
- Quarter: Quarter socks are higher than low-cut socks and usually cover the anklebone entirely. This provides a feeling of stability in the ankle, and alleviates most blistering that could be caused when low-cut socks creep down and expose the skin on the back of the heel.
- Crew: Crew socks go as high as mid-calf. They provide full foot, ankle, and low leg coverage for a variety of activities.

Customer Reviews
SuperbExcellent quality so far—worn weekly for 3-4 hour hard cycling sessions in the Fflorida heat. Highly recommended.
Great trail sock!Saw these on buy 2 get one free special and decided to try them out. Glad I did! Haven't had them long enough to comment on durability, but they do seem like they will last. I love the fit, cushioning and breathability. Stay comfortably tight above the ankle, heel and forefoot cushioned nicely and midfoot design allows for significant breathability. I wear a 10.5 shoe and large sock fits well with no blistering experienced!
